I installed and browsed the Montavista BSP for the MPC5200LITE as a starting
point. So far the best documentation I've found is the source for their
deploy script...

You can extract specific examples of dBUG and u-boot command sequences from
there - both for installing u-boot LOW and booting linux.

The following worked for me to get u-boot going:
$cd u-boot
$make MPC5200LITE_LOWBOOT_config
$make CROSS_COMPILE=/path/to/bin/powerpc-linux-
$su -c "cp u-boot.bin /tftpboot"

#dBUG commands to load u-boot via tftp
set mac 00:01:AF:52:01:xx # see MPC5200LITE doco for how to choose xx value
set client lite.ip.address
set server tftpserver.ip.address
set netmask your.netmask
dn -i -o 0x100000 /tftpboot/u-boot.bin
fe 0xff000000 0xff050000
fp 0xff000000 0xff040000 0x100000
#power off and change link to boot low
#power up to u-boot

I've currently configured u-boot to load my kernel via bootp and nfs mount a
root filesystem built with buildroot (see I did this as follows
(nfsargs line will wrap):

setenv ethaddr 00:01:af:52:01:xx
setenv nfsargs setenv bootargs root=/dev/nfs
nfsroot=\$\(serverip\):/tftpboot/\$\(ipaddr\) console=ttyS0,115200
setenv bootdelay 2
setenv bootcmd bootp\; run nfsargs\; bootm

read u-boot wiki to do it differently:)

NOTE: if you have a Version 2.0 board and want 16MiB flash to actually work
you should ensure J24 is in the 2-3 position (J24 is a 0R resistor on the
bottom of the board).
It is stupid for the jumper to be in the 1-3 position when 16MiB is loaded
but that is the way my board was. Seems like a manufacturing error:(
